Yesterday I've installed a used RX570 and everything was fine, except that my TV only works on VGA for PC, HDMI looks very bad as it's not intended to be used that way, so I was using the HDMI anyway and downloaded drivers, ran Unigine for a couple minutes and everything was OK. Today i've got a DVI to VGA adapter to use the TV VGA. Turning the system on with the adapter plugged didn't worked, so I turned off and turned on again with HDMI, everything OK. Without turning off again I plugged the Adapter again, in the moment I did that the screen gone black (no signal) and the GPU fans gone to full speed, now it's not working anymore, even on HDMI, it just doesn't display anything and the fans stay at max speed. GPU Power indicator still works (no light when plugged, Led on if not plugged). Onboard video is working even with gpu plugged. GPU can't be seen on device manager. Is there something I can do to remedy this?
